One of our most special events of the year is just a month away, the Annual Linux Foundation Collaboration Summit. This Summit is unique because it's the first event we ever hosted (2007 on the Google campus) and aims to bring together Linux Foundation members with other distinguished community members to work on very specific opportunities for Linux. This year, the event will be at the Hotel Nikko from April 3-5.

As we prepare for the Collaboration Summit, we wanted to share with you a little trip down memory lane. This year is the sixth annual event, so this slideshow shares pictures from five years of Linux collaboration. From Google's campus to Austin, Texas to Hotel Kabuki, come with us as we remember why this event continues to be so amazing.
